摘要： Embodiments of this application provide a packet transmission method, a communication apparatus, and a communication system. A target transport layer proxy network element establishes a fourth transport layer connection based on a first context of a source transport layer proxy network element, where the first context is a context about packet transmission of the source transport layer proxy network element on a first path. If the target transport layer proxy network element receives first indication information, and the first indication information indicates that application context migration between a first application server and a second application server is completed, the target transport layer proxy network element performs transport layer processing on a packet on a second path based on a second context of the target transport layer proxy network element, and transmits, on the second path, a packet obtained through the transport layer processing. Hence, a packet loss can be avoided.

摘要： Embodiments of the present invention disclose a communication method and a device. The method includes: determining a first CU-UP and a UPF network element that correspond to a QoS flow, where an access network device to which the first CU-UP belongs supports at least two CU-UPs; determining a first PDB for transmitting the QoS flow between the first CU-UP and the UPF network element; and sending the first PDB to the access network device, where the first PDB is used by the access network device to schedule an air interface resource. In the embodiments of the present invention, after the CU-UP corresponding to the QoS flow is determined, the PDB of the CU-UP corresponding to the QoS flow may be sent to the RAN device.

摘要： An embodiment of the present invention provides a NFV based fault processing method. The method includes: determining a NFVI fault; obtaining self-healing policy information used to indicate whether to perform a self-healing operation on the NFVI fault; and performing the self-healing operation on the NFVI fault when the self-healing policy information indicates that the self-healing operation is to be performed on the NFVI fault. Therefore, time for reporting and making a fault analysis for the infrastructure fault can be saved, the infrastructure fault is rectified as quickly as possible, a fault processing delay is reduced, and system performance can be improved.

摘要： This application provides a communication method and apparatus. The method includes: A first device determines information about service flow arrival time, where the information includes time at which a first service flow (a periodic service flow to be transmitted between an access network device and a user plane network element) arrives at a second device. The first device determines information about service flow sending time based on the information about the service flow arrival time. The first device indicates the second device to wait, after receiving the first service flow, until the service flow sending time to send the first service flow. If the first service flow is an uplink service flow, the second device is the access network device or a translator corresponding to the access network device; or if the first service flow is a downlink service flow, the second device is the user plane network element.

摘要： According to a communication method and a communications apparatus, in a process in which an access network device serving a terminal is handed over from a source access network device to a target access network device, a user plane function network element may transmit first information to the source access network device. The first information is used to indicate that the user plane function network element bicasts downlink packets to the source access network device and the target access network device, so that after determining that a data packet received before the first information is sent to the terminal, the source access network device triggers an air interface handover, to avoid a packet loss in a handover process, or so that the source access network device synchronizes a PDCP SN of the source access network device with a PDCP SN of the target access network device.

摘要： Embodiments of this application disclose a method and a device therefor, applied to a scenario of Ethernet packet transmission. In an example method, a first device receives a first packet. Load data in the first packet includes padding redundant data. The first device deletes the padding redundant data. The first device generates a second packet. Load data in the second packet is payload data obtained after the padding redundant data is deleted from the first packet. The first device sends the second packet to a second device.
